Neutral divalent carbon species released as reaction intermediate in reaction

Neutral divalent carbon species released as reaction intermediate in reaction of ethylene is

Options

(a) carbocation
(b) carbene
(c) carbanion
(d) free radical

Correct Answer:

carbene

Explanation:

Carbocation is the +ve charged carbon species. e.g. ⁺CH₃, ⁺C₂H₅.
Carbanion is the -ve charged carbon species. e.g. ⁻CH₃, ⁻C₂H₅.
Free radical is the trivalent neutral carbon species with an electron. e.g. CH₃, C₂H₅. Carbene is the divalent neutral carbon species with two free electrons. This is two types, such as single and triplet. e.g. :CH₂(triplet), :CH₂(singlet).
